From: Ammonia borane positively regulates cold tolerance in Brassica napus via hydrogen sulfide signaling
Schematic of the mechanism underlying ammonia borane (AB) positively regulating cold tolerance via hydrogen sulfide (H2S) signaling in B. napus. A rapid response of H2S production was observed after AB addition under cold stress. This enhanced H2S signal could enable plant to cope with cold stress via maintaining ICE1-CBF-COR pathway and redox homeostasis (especially)
